Surrender to Supreme Being means that a believer completely gives up his own will and subjects his thoughts, ideas and deeds to the will and teachings of a higher power. It may also be contrasted with Submission. Surrender is willful acceptance and yielding to a dominating force and their will. Several gurus teach their disciples the importance of surrender to God or to themselves, as part of the guru-disciple relationship.
For Example:-
According to the Shrimad Bhagavad Gita, Lord Krishna said the following to the warrior Arjuna, who became his disciple:
I consider the yogi-devotee-who lovingly contemplates on Me with supreme faith, and whose mind is ever absorbed in Me-to be the best of all the yogis. —Chapter 6, Verse 47
After attaining Me, the great souls do not incur rebirth in this miserable transitory world, because they have attained the highest perfection. —Chapter 8, Verse 15
… those who, renouncing all actions in Me, and regarding Me as the Supreme, worship Me… For those whose thoughts have entered into Me, I am soon the deliverer from the ocean of death and transmigration, Arjuna. Keep your mind on Me alone, your intellect on Me. Thus you shall dwell in Me hereafter. —Chapter 12, Verses 6-8
Surrendering or taking sharanagati, does not mean that you abandon your worldly duties. As Lord Krishna states in the final chapter of the Gita, “Discharge your duties in the world. But fix your mind on me…. Take refuge in me and you will overcome all obstacles and you will enjoy enduring happiness.”
